Dimercaptosuccinic Acid

The official chemical name of Dimercaptosuccinic Acid is meso-2,3 - Dithiobutyric Acid. It belongs to the class of dicalcic acid containing mercapto groups. The two active mercapto groups in its molecular structure are the core functional groups and are the key factors enabling its ability to chelate heavy metals. Dimercaptosuccinic Acid is a white crystalline powder with uniform and loose crystal form. If exposed to the air for a long time or stored improperly, the mercapto groups will be oxidized and the color will gradually turn yellowish and dark. It has a special odor similar to garlic, which is a common characteristic of mercapto compounds and is a normal odor of the raw material itself. At room temperature, Dimercaptosuccinic Acid is almost insoluble in water and easily soluble in alkaline aqueous solutions. It is only slightly soluble in methanol in organic solvents and insoluble in most common lipid-soluble solvents.

DMSA is one of the few oral-effective heavy metal chelating agents. It has particularly strong specificity in binding to lead ions. It can not only rapidly reduce the lead load in blood and soft tissues, but also reduce the absorption and retention of lead in the gastrointestinal tract. It is currently recognized as the core functional component in the field of lead elimination.

It has a clear chelation and excretion effect on various toxic heavy metals such as mercury, arsenic and copper. It can recover the metal ions that have combined with the body's enzyme system, restore the normal physiological activity of sulfhydryl enzymes, and reverse the metabolic disorders caused by heavy metal poisoning.

DMSA also has certain antioxidant and organ-protective effects. It can alleviate the oxidative stress response induced by heavy metals, eliminate excessive free radicals, and reduce the secondary damage to metabolic organs such as the liver and kidneys during the detoxification process.

DMSA is widely used in the preparation of various formulations such as lead-removing capsules and oral detoxification solutions. It is the preferred oral component for the treatment of moderate to severe lead poisoning in both adults and children.

The DMSA powder can be directly used in industrial wastewater treatment scenarios, helping to ensure that industrial wastewater meets discharge standards. It can also be applied in soil heavy metal pollution remediation and contaminated site treatment projects, serving as an environmentally friendly chelating agent to reduce the bioavailability of heavy metals in the environment.

In the fields of biochemical research, toxicology research and environmental detection, DMSA is a commonly used standard chelating agent, which can be applied to the study of the toxic mechanism of heavy metals and the screening experiments of detoxification drugs, as well as the detection and pretreatment of heavy metal content in environmental samples and biological samples.
